Description
Technical Field
The invention relates to the technical field of concrete construction, in particular to a formwork erecting method for lattice beams and lattice columns of an oversized inclined plane broken stone slope.
Background
With the continuous development of society, many engineering projects relate to the excavation and supporting operation of side slopes. At present, in the construction process of a slope concrete formwork, a wood-rubber plate with the thickness of 1.8cm is assembled according to the design size in the conventional method, 5 multiplied by 10cm square wood is adopted as braces, the surface of the formwork is cleaned and brushed with a release agent, a top formwork is pressed on a side formwork and then nails are nailed along the side formwork, the top formwork and the side formwork are nailed together, and the distance between the nails is 30cm; then pressing two 5 multiplied by 10cm square timbers on the upper part of the top die to be used as braces; the top die is provided with a feed opening every 1.5m, a single-row frame is erected on the full slope surface on the upper part of the top die after the top die is installed, the single-row frame can be used as a passage and can also enhance the integrity and the anti-floating performance of the template, the distance between the single-row frames is 1.5m multiplied by 1.5m, and the single-row frame is connected with a template reinforcing system through a fastener or a steel bar. However, because the slope angle is generally large, the flatness of the base layer of the slope is poor, the firmness of the limiting fixed point of the beam column cannot be mastered, the phenomenon of top mold floating or beam column displacement is easy to occur, and the construction quality is finally influenced.
Disclosure of Invention
The invention aims to overcome the defects and provides a top template supporting method for lattice beams and lattice columns of oversized inclined plane broken stone slopes, which can ensure stable, safe and reliable supporting of the top template and can improve the template supporting efficiency.
In order to achieve the above object, the present invention is realized by:
a method for erecting the lattice beams and columns of the slope with very large slope of broken stone includes
Step 1, selecting a steel plate: selecting a steel plate with the thickness of 3mm and the standard length of 2m;
step 2, manufacturing a U-shaped steel top die: bending a steel plate, wherein the bending width of the steel plate is +13.6mm of the cross section size of the beam column, and further, folding the side edges of the two sides of the steel plate by 50mm;
step 3, arranging pouring holes with beam width of 400mm in the middle of the U-shaped steel top die, welding phi 16 screw holes on two sides of each pouring hole, enabling the bottoms of the screw holes to be flush with the steel plate, and arranging three rows of screw holes in each pouring hole;
step 4, buckling a U-shaped steel top die on the top surface of the beam column, arranging a fastener at the position of 300mm of the side surface, fastening the fastener step by step, connecting and reinforcing the fastener with batten of a side plate of the beam column, and arranging phi 20 soil anchor rods at intervals of 600mm to be connected with the slope;
and 5, reinforcing the pouring hole by using a bolt.
According to the field construction measurement and calculation, the floating phenomenon of the top mould of the on-site lattice beam and lattice column is 13.5% and the section size exceeds the specification requirement and is 15% by using a conventional reinforcing method; after the construction mode of the U-shaped steel top die provided by the invention is used, the upward floating phenomenon of the top die is 4%, and the section size meets the requirements. The construction speed is 20 percent faster than that of the original conventional scheme. After the U-shaped steel top die is used, the construction efficiency is improved, and the construction quality is guaranteed.
